Aim:

The aim of this project is to create a game without screen allowing to kids to understand computing logic.

Here the project is using to recreate old instrument music with perforated card. Like the Sankyo instrument, see behind.

Instead of to be a mechanical instrument, here it is a electronic one. it measures the tension using 4 column. Using paper sheet with whole you can create music note (C, D, E, F, G, L, B)

How it's work:

1. With a paper sheet at create 4 columns.
2. Pierce the paper using the schematic behind to reproduce note
3. slide the paper in the electronic game and enjoy that song
4. When there is a whole, the connection is done with a resistance and the tension change.
   1. There is 4 Resistances and using these we can trigger the 7 music notes following that table

	R1	R2	R3	R4
C	X
D	X	X
E			X
F		X
G		X	X
L	X			X
B				X
Silence	X	X	X	X

Example of a sheet:
